Patterns are made using straight lines and arcs. a) Pattern A (one row) Pattern B (two rows)

(2)

More rows are added to Pattern B so that

number of straight lines : number of arcs = 7:6

How many rows are added?

Your final line must say

rowGroddat

Complete the equation of the line through (−10,3) and (−8,−8). use exact numbers.

Rhombus adef is inscribed into a triangle abc so that they share angle a and the vertex e lies on the side bc . what is the length of the side of the rhombus if ab=c, and ac=b.

Assume that females have pulse rates that are normally distributed with a mean of mu equals 72.0 beats per minute and a standard deviation of sigma equals 12.5 beats per minute. complete parts (a) through (c) below. a. if 1 adult female is randomly selected, find the probability that her pulse rate is between 65 beats per minute and 79 beats per minute. the probability is? b. if 16 adult females are randomly selected, find the probability that they have pulse rates with a mean between 65 beats per minute and 79 beats per minute. the probability is? c. why can the normal distribution be used in part (b), even though the sample size does not exceed 30?
